Farangis is a fine-tuned adapter for Qwen3-14B that brings native Farsi conversational ability and chain-of-thought (CoT) reasoning to the base model. It was trained on a mix of reasoning and non-reasoning Persian data so it can hold a natural conversation and think step-by-step in Farsi when a task calls for it.

Model Details

Base model: Qwen/Qwen3-14B
Adapter type: LoRA (fine-tuned adapter, not a full merge)
Language: Farsi (Persian), with English capability inherited from the base model
Capabilities: general conversation, instruction following, and chain-of-thought reasoning — all in Farsi

Training Data

Farangis was trained on a mix of two datasets to balance conversational fluency with reasoning ability:

Dataset	Type	Purpose
`artindnr/Persian-Thinking`	Reasoning	Teaches the model to generate explicit chain-of-thought traces in Farsi before producing an answer
`xmanii/maux-gpt-sft-20k`	Non-reasoning (SFT)	Grounds the model in natural, direct Farsi conversation and instruction-following

Mixing reasoning and non-reasoning examples was intended to let the model reason step-by-step (CoT) when a problem needs it, while still answering straightforward conversational prompts directly and naturally, without over-explaining or forcing unnecessary reasoning traces.

Intended Use

Farsi-language chat assistants and conversational agents
Tasks that benefit from visible step-by-step reasoning in Farsi (math, logic, multi-step Q&A, analysis)
General-purpose Farsi instruction following

How to Use

Farangis is distributed as a LoRA adapter on top of Qwen3-14B. Load the base model and apply the adapter with 🤗 PEFT:

python

from unsloth import FastLanguageModel

BASE_MODEL = "unsloth/qwen3-14b-unsloth-bnb-4bit"
ADAPTER_REPO = "artindnr/qwen3-14b-model-persian-cot-adapter"
MERGED_REPO = "artindnr/farangis"

# Load base model + tokenizer
model, tokenizer = FastLanguageModel.from_pretrained(
    model_name = BASE_MODEL,
    max_seq_length = 2048,
    dtype = None,
    load_in_4bit = False,
)

# Attach the LoRA adapter from the hub
model.load_adapter(ADAPTER_REPO)


messages = [
    {"role" : "user", "content" : "Continue the sequence: 1, 1, 2, 3, 5, 8,"}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize = False,
    add_generation_prompt = True, # Must add for generation
)

from transformers import TextStreamer
_ = model.generate(
    **tokenizer(text, return_tensors = "pt").to("cuda"),
    max_new_tokens = 512, # Increase for longer outputs
    temperature = 0.7, top_p = 0.8, top_k = 20,
    use_cache = True,
    streamer = TextStreamer(tokenizer, skip_prompt = True),
)

Limitations

As a LoRA adapter, output quality is bounded by the capabilities of the Qwen3-14B base model.
Reasoning traces are generated in Farsi and, like any CoT output, are not a guaranteed reflection of the model's internal computation — treat them as an explanation, not ground truth.
Trained primarily on Farsi data; performance on other languages should be expected to track the base model's baseline, not this adapter's tuning.
Not evaluated for safety-critical, medical, legal, or financial use.
